Question 1

What occurs when an atom absorbs a photon?

  • Photon energy increases
  • An electron transitions to a higher energy level
  • Thermal energy is released

💡 Hint: Think about what it means for an electron to be 'excited'.

Question 2

True or False: The dark lines in an absorption spectrum indicate the energy that was emitted.

  • True
  • False

💡 Hint: Consider whether energy is absorbed or released during electron transitions.

Question 1

Consider a hypothetical element that absorbs wavelengths of 450 nm, 500 nm, and 600 nm. If you were to see its absorption spectrum, which colors would be darkest?

💡 Hint: Think about what happens to the light when it encounters the element.

Question 2

Explain the importance of using absorption spectra in determining the composition of distant stars.

💡 Hint: Consider how distant observations rely on light gathered from those stars.
